The probability of blind construction, in order to help managers obtain more accurate construction data information, to ensure that the cost can be controlled within an effective range, and correspondingly reduce the waste of labor, materials, and mechanical equipment investment, and the HVAC installation greatly improves the economy benefit. In addition, the new HVAC technology can also continuously increase the cooperation capabilities of various projects, thereby ensuring that the project can be completed within the specified time, and effectively improving the use efficiency of manpower, materials and mechanical equipment, and overall improving the management level of the project and the construction of the project. the quality of.

On the other hand, various construction links have strengthened the connection, which can greatly reduce the occurrence of problems such as slow construction progress and low construction efficiency due to difficulties in cooperation, greatly enhance the integration degree of electromechanical installation engineering, and even promote it to a certain extent. The further development of the enterprise has also brought certain economic benefits to the enterprise.

At present, with the improvement of the automation upgrade speed of the heating system, the automation level of all kinds of equipment is also increasing, which makes the boiler mechanism etc. to be used to a certain extent, effectively ensuring that the heating system remains more stable. , Smooth operation.

In addition, with the continuous use of household metering, my country's legal planning in environmental protection, energy saving and consumption reduction has become more complete, and to a certain extent, the national awareness of environmental protection has been greatly improved, and the application of household metering has also been obtained. A greater use space. The vigorous promotion of boiler energy-saving technology will drive the research of related automated machinery and equipment, which in turn will make the combustion of coal more harmless and greatly improve the efficiency of energy use. At the same time, the use of clean energy will be expanded, and as people's awareness of environmental protection increases, clean energy such as solar energy will gradually replace traditional energy.

1. The core technology of integrated refrigeration room

The core technology of the integrated refrigeration machine room is that the relevant working technology researchers make certain improvements to the current design through the use of advanced three-dimensional simulation technology, and carry out corresponding designs for the energy-saving of the central air-conditioning system machine room. The heat exchanger unit, compressor unit, electrical control system and hydraulic module are integrated in the factory to a certain extent, and then they are assembled accordingly.

At the same time, to optimize the configuration of related equipment, different degrees of cooling capacity can be selected in the factory, and at the same time, the indoor and outdoor installation type with a 24-hour maintenance structure can also be selected. The integrated refrigerating machine room can ensure that the air-conditioning system can be in an optimized state during operation, thereby achieving a high degree of energy saving.

And, at the same time, the core technology of the integrated refrigeration room can also make the different associated control systems of the air-conditioning system perform corresponding coordinated operation, which not only improves a certain operating efficiency, but also greatly reduces energy consumption.

In addition, the integrated refrigeration machine room is mainly through the clever use of the system integration science and technology carried by itself, and at the same time, it uses simulation check to divide the equipment of the system refrigeration station into modules, and then install it in high-precision steel. On the structural platform, then carry out the corresponding system cleaning activities and so on.

Secondly, according to the actual situation and actual characteristics of the project, the integrated refrigeration room can be divided regularly to facilitate transportation to the construction site. When assembling them, the main goal of system integration technology is to optimize the overall system functions to a large extent.

2. BIM Technology

BIM technology can optimize the design of the electromechanical installation project, and then use the electromechanical components to establish a scientific and reasonable three-dimensional information model, and then help the staff to make corresponding decisions.

2.1 Synthesis, demonstration and virtual creation of pipeline balance

Through the full use of the three-dimensional information model, the collision check of the pipelines in each electromechanical installation project is carried out. In addition, in order to achieve the appropriate effect of the pipeline layout, the staff can continuously use the adjustment pipelines to perform spatial The layout of the system can effectively reduce the waste of man-hours, human resources, materials and other resources caused by rework. In the in-depth pipeline design, the virtual erection project of the electromechanical construction project can be completed before the construction through the three-dimensional information model established for each interrelated electromechanical component. The complete display of the construction results can make the decision of the project management personnel and the construction fully displayed in front of people.

2.2 Intelligent calculation and decision-making assistance

The BIM technology in the new HVAC technology of mechanical and electrical installation engineering can effectively improve the work efficiency of the staff to a certain extent. The staff can make full use of the calculation software in the BIM technology to change the traditional manual calculation method, and the physical quantity can be calculated quickly and accurately from the electronic drawing. In addition, the three-dimensional information model can also ensure the traceability, accuracy, and timeliness of the data, and calculate the quantity of a certain HVAC system in detail and accurately, and then contribute to the purchase of construction materials, the planning of the construction schedule, and the calculation of the data. Provide effective assistance in terms of human supply, which in turn makes the staff's work decisions more accurate.

2.3 Machine-made metal inner thermal insulation duct

The machine-made metal inner thermal insulation air duct is a kind of air duct that saves energy and reduces consumption and reduces noise by using the form of inner lining for heat preservation. The main material used for the outer shell of the machine-made metal inner thermal insulation air duct is metal thin steel plate. The material is mechanically pressed to form a mold, and then the composite coating is wrapped by the glass fiber thermal insulation lining and the steel plate air duct. The nails are fixed accordingly, and a series of automated processing are carried out at one time. This kind of thermal insulation material has a certain function of resisting falling off and preventing mildew.

Therefore, it can be used in air conditioning, ventilation and smoke exhaust systems. In addition, compared with the production of traditional external thermal insulation metal air ducts, the machine-made metal internal thermal insulation air ducts are more in line with the requirements of the current green construction concept to a certain extent. First of all, the mechanism's metal internal thermal insulation air pipe is processed and formed by the factory at one time, and the construction staff only needs to hoist and install according to the construction drawings.

Therefore, it is quicker to install. In addition, the machine-made metal inner thermal insulation air duct does not need to reserve a working space for the air duct insulation, and it can be installed on the top, which saves installation space to a certain extent.
